Additional information

Adsorption / desorption

Parent compound valeryl chloride and hydrolysis product valeric acid: Adsorption to solid soil phase is not expected.

However, the assessment of the adsorption potential of the parent compound may be of low relevance, due to the rapid hydrolysis of the acid chloride in aqueous solutions.

Henry`s Law constant

Parent compound valeryl chloride From the water surface, the substance will rapidly evaporate into the atmosphere.

Hydrolysis product valeric acid From the water surface, the substance will not evaporate into the atmosphere.

However, the assessment of the volatility of the parent compound may be of low relevance due to the rapid hydrolysis of the acid chloride in aqueous solutions

Distribution modelling

Parent compound valeryl chloride: Over time, the substance will preferentially distribute into the compartments air (93.5%) and water (6.5%).

However, the model estimation is of low relevance due to the rapid hydrolysis of the acid chloride in aqueous solutions.

Hydrolysis product valeric acid: Over time, the substance will preferentially distribute into the compartments water (93.3%) and air (6.36%).
